K&N Oil Filter KN-303 Videos

K&N Oil Filters are designed to satisfy the needs of racers and engine builders as well as the average motorcycle or ATV owner who wants the best oil filter available. K&N Oil Filters trap harmful contaminants while the filter's construction allows for high oil flow rates.

The 'spin-on' oil filters feature a heavy-duty metal can. Most have a 17mm nut affixed onto the end that allows for easy installation and removal. The 17mm nut is cross-drilled so racers can safety wire the filter.

My oil has never been so filteredededed.
Its an oil filter...gets the job done. This purchase should be a no brainer over the stock.

Worth every penny!
I've always liked how easy it is the wrench top makes the filter removal a breeze.
The filters are nicely packed and wrapped in plastic so there's no dirt or box shavings stuck inside like the last time i got a kawi filter.

Simple installation
Gone are the days of prying an oil filter off with whatever tool that works. The K & N oil filter makes quick work of installation with the addition of its appropriately sized 17mm nut built into its assembly.

Great filter with added features
I use K&N filters on all of my sportbikes. From reviews and testing it seems that the quality of the filter for it's intended purpose (filtering oil) is on par or better than other high performance oil filters, and that the internal construction is of high quality. The added features of having a nut on the top of the filter for easy removal, and the fact that the filter is pre-drilled for safety wire makes it super easy to just change my oil and go.

Never a problem
I have never had a problem EVER going with a K&N product and I'm sure I never will. Worth the money, and the bike always runs better with a K&N filter.

Quality filter
Simple oil filter that does what it is intended to do. The nut on top makes it especially easy to remove, unlike the stock filter. Good buy.

Hieu P asked:Will this fit a 2014 Kawasaki Ninja 300 ABS? It says that it will fit a 2013 model but it doesn't specifically say 2014, though I don't think the size of the oil filter changed but I just want to make sure.May 1, 2015
